Abstract-This paper presents the daily, monthly and annual solar irradiation in Kangar. They are observed and analyzed to obtain the potential of Sinusoidal Pulse Width Modulation Transformerless Photovoltaic Inverter (SPWM TPVI) system application. It is due to the SPWM TPVI system is operated directly by PV module, therefore an optimization sizing of the system is studied in this paper. The optimum sizing is based on the solar irradiance, temperature, PV power and demanded power of SPWM TPVI. They are created in mathematical modeling. The results show that the average monthly solar radiation for the year of 2015 is 407.0 W/m 2 or 4861.44 Wh/m 2 . It is classified in very high solar radiation and indicates that the sky in Kangar is very clear and very suitable for generating the SPWM TPVI system. The optimum PV module string number is 21 (difference between the generated power and demanded power is zero). It is due to there is three PV modules in one string that connected in series, therefore the total number of PV module is 63 to generate the 1200 W SPWM TPVI system.
